A network interworking system is provided for connecting a voice call between a mobile terminal in a wireless packet network and a mobile terminal in a mobile communication network. A home location register (HLR) registers therein location information of terminals and a subscriber profile. An access point controller (APC) converts data between the mobile communication network and the wireless packet network upon receipt of an origination message including a terminal identifier of a called terminal, and transmits a call connection request to the called terminal. A mobile switching center (MSC) detects a location of the called terminal through the HLR upon receipt of the call connection request from the APC, and transmits a paging message to the detected location of the called terminal. A base station system (BSS) transmits the paging message from the MSC in the mobile communication network to the called terminal.

There is proposed a mechanism for controlling a communication connection of a user equipment in a communication network. The communication network comprises at least a core network subsystem having at least one core network control element, and a first access network subsystem and at least a second access network subsystem. On one hand, when it is detected that at least one connection parameter of a communication connection of the user equipment can not be maintained by the first access network subsystem, a connection modification message is sent to the core network control element. The core network control element responds with an acknowledgement message the acknowledgement message comprising an instruction parameter for instructing that the communication connection of the user equipment is to be changed to the second access network subsystem being determined to having the capability to provide the connection parameter. On the other hand, when a change of a communication connection of the user equipment from the first access network subsystem to the second access network subsystem is to be performed, it is checked whether or not the cell change is executable. On the basis of the result of the checking step, a message is sent to the core network control element comprising an information element about the execution of the change of the access network subsystem.

Disclosed is an apparatus and method for recovering a communication link between a Mobile Station (MS) and a Base Station System (BSS) in a mobile communication system when the communication link is disconnected while a communication service is in progress. When detecting the disconnection, the MS stores information of the communication link. If the MS acquires synchronization with the BSS within a predetermined time period from the detection, it resumes the communication service through the communication link. Upon the disconnection, the BSS stores resource and other information of the MS. If the BSS detects that the MS has acquired synchronization with the BSS within the predetermined time period from the disconnection, the BSS resumes the communication service through the communication link. This ensures a stable communication service in a mobile communication system that has many radio dead zones where the MS cannot normally receive services.
